Add unused code pass
In order to find more examples of dead code we must create liveness variables
and scan after type resolution. In this case, if a function is unused and it calls
another function the 2nd function is now unused since the caller is not used etc.
This is a WIP but demonstrates the pattern we can follow to add more dead code
analysis warnings like rustc does.
